Abstract
This paper presents two concepts to adapt or transform the traditional water management system to suit modern socioeconomic conditions; (a) improved tank management with water control; and (b) an alternative land-management system to control runoff and erosion to recharge groundwater and sustain irrigation wells. Model calculations for the first concept show that improved tank management with a water control system of closing sluices on rainy days would save enough water to irrigate an additional 20% of the command area at a 17%lower risk of crop failure. Investment in an organization to employ and supervise tank water controllers can be justified by the exp0732ected returns from the increased area under irrigation. The second concept can be expected to generate substantial increases in net returns and employment.
